The question I alluded to above concerns a phased panel upgrade and interoperability during and after the upgrade.
Current panel includes a Dynon D100 networked to a D-10A, AP-74 and 2 SV-32 servos. Radio stack is all Garmin: GMA-340/SL-30/SL-40/GPS396. Nice 20th century VFR set up.
A few projects (new wings and speed mods) compete for time and $ for a full panel upgrade. With planning, the 375 may offer a phased upgrade path to get ADS-B Out compliant and get the benefits of ADS-B In, but I want to ensure a few items work in phase 1, and keep the phase 2 transition somewhat simple.
Phase 1 would be replace the 396 with the 375. Stack would be 340/375/SL-30/SL-40.
My first question here is, will the 375 provide steering commands (HDG/TRK/NAV) to the legacy Dynon equipment I have now? Is there a serial output for this data from the 375, such as the 396 puts out (via the blue wire to pin 22 on the D100)? Early research indicates I would need to add an HS-34 to the panel, to provide the 429 data to the legacy Dynon network and AP. If Levi, Dynon (or maybe the local pro Brian C) could confirm, it would be much appreciated.
Second, related question, is there a remote-mounted 429 box (from Dynon, Advanced or Garmin), that could be used instead of the HS-34, that would provide the data to the legacy Dynon network and AP, that I could then use in phase 2 of the upgrade, when I'll replace the main D-100 PFD with a G3X Touch, AFS 5500, or Skyview? Early research indicates the legacy Dynon/HS-34 protocols are different from the next gen Garmin, Advanced and Dynon 429 modules, but just want to check with this group of pros.
Final panel would have the same radio stack, with a new PFD and AP controller (Garmin or Advanced/Dynon, to match the PFD), and the D100 would become the right seat EFIS.
Thanks for any answers/info!
Cheers,
Bob
